21. L.A. Clippers – 2016
The Clippers have a terrible postseason record because they always choke. They’ve had some great players over the past decade but haven’t been able to capitalize. Unfortunately, that was the case again in this series against the Trailblazers. It didn’t help that Chris Paul broke his hand in Game 4 (via The Guardian).

This was a major turning point because he was their star guard. Then a leg injury took Blake Griffin out of contention. Suddenly, the Clippers lost another elite star and couldn’t replace them. Portland took advantage and knocked them out of the playoffs.
